Description
Technical field
The present invention relates to animal and feed nutrition fields, and in particular to a kind of side for improving milking sow lactation phase feed intake
Method.
Background technique
It is in recent years that in pig production, sow lactation period feed intake is high, excessive weightlessness causes sow service life to shorten
It is next generally existing, and always affect the problem of pig breeding industry.
With the continuous development of modern genetic breeding science, the characteristics of sow is presented are as follows: adipose tissue reduces, mature weight
Increase, sexal maturity shifts to an earlier date and feed conversion rate is higher.Limit the maximum performance of sow reproductive performance: the reduction of feed intake, mother
Pig lactation amount is inadequate.
Since feed intake is inadequate during lactation for sow, and litter size is more, and sow passes through to meet the needs of lactation
Itself is adjusted, the needs for decomposing intracorporal fat to meet mammary gland to energy, therefore the case where lactation period sow is lost flesh occurs.It connects
Heel is that oestrus of sow interval extends, and is especially influenced on first farrowing sow bigger.Furthermore number of eggs ovulated drop next time can be made
It is low, directly affect the efficiency and birth piglet number of breeding；Importantly, sow weight loss between lactation period is too big will to make mother
Pig service life greatly shortens.The service life of domestic sow is averagely in 4-5 tire, and wherein half is just washed in a pan in the first-born
It eliminates, causes very huge economic loss to pig production.How to improve sow lactation period feed intake have become pig farm most concerned about, most
Technical problem to be solved.
In the prior art, the nutrition that each period in the production cycle entire for sow uses is studied, as in
A kind of pregnant sow method for breeding disclosed in state patent CN104872411B, after the feed of feeding is including feed, gestation before gestation
Feed and breast milk phase feed, for method for breeding the following steps are included: 1) three phases fed before, during and after period of pregnancy point, early period uses gestation
Preceding forage feed is pregnant 0~40 day, feeding material 1.5~1.8 ㎏/head/day；Mid-term is pregnant using forage feed before gestation
40~80 days, feeding material 2.0~2.5 ㎏/head/day；2) later period using forage feed after gestation, that is, is pregnant 80~110 days, feeding
Expect 3.0~3.4 ㎏/head/day；3) lactation period uses lactation period forage feed, and second day postpartum with 1.4kg/ head/day, pressed
0.4kg/ days doses are incremented by, until being added to 3.5kg/ head/day；Wean preceding 5 days with 0.5kg/ days doses successively decrease up to
Until 1.8~2.0kg/ days.The patent is pregnant to sow using feed after feed, gestation before universal gestation and breast milk phase feed
